The state-of-the-art anodes for solid oxide fuel cells (SOFCs), composed of Ni and YSZ (yttria-stabilized zirconia), suffer significantly from Ni-catalyzed carbon deposition and the ensuing degradation of the anode performance. Here, we address these issues through the application of a simple, scalable, cost-effective ceramic coating method known as cathodic electrochemical deposition (CELD). We show that just 1 minute of CELD treatment creates an oxide coating that significantly enhances activity for hydrogen (or methane) electrooxidation relative to the uncoated substrate. We further show that the CELD coated anode has exceptional resistance to carbon deposition, suggesting it as a feasible solution for the direct use of hydrocarbon fuels in SOFCs. |
